Methyl Cap Stabilizer?

Methyl TinSteeilizers yog ib hom orgoticin sib xyaw ua ke siv los ua cua sov stabilizers hauv kev tsim cov polyvinyl chloride (PVC) thiab lwm cov yas polymers. Cov cabilizers pab tiv thaiv lossis txo cov thermal degradation ntawm PVC thaum ua thiab siv, yog li ua kom cov khoom siv ua haujlwm ruaj khov thiab ua haujlwm. Ntawm no yog cov ntsiab lus tseem ceeb txog methylin stetilizers:

Tus qauv tshuaj:Methylin Stetilizers yog Orgototin Tebchaw muaj cov methyl pawg (-ch3). Piv txwv muaj xws li methyl tin mercaptides thiab methyl tin carboxylates.

Ruaj Khoo Zog:Cov stabilizers ua haujlwm los ntawm kev sib cuam tshuam nrog chlorine atoms tso thaum muab PVC thermal degradation. Lub methyl tet stetilizers neutralize cov clorine radicals, tiv thaiv lawv los ntawm kev pib ua rau muaj kev cuam tshuam ntxiv.

Cov Ntawv Thov:Methylin Stetilizers tau siv dav hauv ntau cov ntawv thov PVC, suav nrog cov kav dej, fittings, khoom, thiab cov yeeb yaj kiab. Lawv tau tshwj xeeb rau cov kev mob siab ua haujlwm hnyav, xws li cov kev sib ntsib thaum lub sijhawm extrusion lossis txhaj tshuaj molding.

Cov txiaj ntsig:

Siab thermal stability:Methyl T Cob pab pawg muab cov khoom ruaj khov ua kom ruaj khov, tso cai PVC kom tau txais cov chaw kub ua kom kub.

Cov xim ua tau zoo:Lawv pab txhawb kom tswj cov xim muaj zog ntawm cov khoom siv PVC cov khoom lag luam los ntawm kev txo qis los ntawm kev cuam tshuam thermal.

Zoo heev Cov Kev Kub Siab Kub:Methyl T Cobilizers pab PVC cov khoom txwv tsis pom lub sijhawm thaum tshwm sim los ntawm kev kub thiab ib puag ncig.

Kev Txiav Txim Siab:Thaum ua tau zoo, kev siv cov orgototin tebchaw, suav nrog methylin stabilizers, tau ntsib kev txhawj xeeb thiab kev txhawj xeeb txog kev noj qab haus huv uas cuam tshuam nrog tin tebchaw. Hauv qee thaj tsam, cov kev txwv los yog cov neeg tuaj yeem raug laij tawm ntawm qee cov haujlwm orgototin stabilizers.

Hloov chaw:Vim tias kev hloov pauv hloov, kev lag luam PVC tau tshawb xyuas kev hloov pauv thaum sov cov stabilizers uas muaj kev cuam tshuam ib puag ncig ib puag ncig. Cov tshuaj calcium raws li stabilizers thiab lwm cov kev xaiv tsis muaj txiaj ntsig yog siv nyob rau hauv teb rau kev cai lij choj.

Nws yog ib qho tseem ceeb kom nco ntsoov tias cov cai tswj hwm yuav txawv ntawm thaj tsam, thiab cov neeg siv yuav tsum ua raws li cov cai thiab cov lus qhia hauv ib cheeb tsam thiab siv PVC stabilizers. Ib txwm sab laj nrog cov khoom siv, cov lus qhia kev lag luam, thiab cov cai tswj hwm muaj feem rau cov ntaub ntawv stabilizer thiab ua raws li.
